On the triviality of inhomogeneous deformations of $\mathfrak{osp}(1|2n)$

We specify a symmetrized mixed-oscillator deformation family of $B(0,n)=\operatorname{osp}(1|2n)$, with even mixed coefficients and one odd square-zero parameter. For every $n\geq1$, we derive its bracket from a faithful oscillator realization and exhibit an odd cochain whose coboundary is the recov
